I love the new assault grens which enable German players to easily take the fight to the soviet player early game. However a wise Soviet player will get m3+flamers to counter this. In order for the German player to counter that they must then go t2 for upgunned scout cars. At which point the soviet player go either go at-nades or guards and so the old meta resumes. Lots of players see this new commander as overpowered however they just haven't realized what counters the assault grenaiders yet =P.
The problem is that soviets usually start off with a couple of conscripts first. You can't really get the scout car out until the second engagement. Assault grens basically let's the Germans easily win the first engagement which is a pretty big head start. The only way to win the initial engagement would be to build T1 immediately, but you wouldn't even know that he has assault grens by then.
